WAVE-MOTOR.

Specification of Letters Patent.

Patented Dec. 12, 18116.

Application filed January 31, 1916. Serial No. 75,424.

To all whom it may concern Be it known that l, Josnrrr LACHANOE, a citizen of the United States, residing at Los Angeles, county of Los Angeles, and State of California, have invented certain new and useful Improvements in lVave-lnlotors, of which the following is a specification.

My invention relates to motors and particularly to wave operated motors.

The object of my invention is to provide a motor for transmitting the energy from a wave actuated member to the work at a uniform rate or power.

A further object of my invention is to provide a device of the class mentioned whereby the power shaft may be actuated by any desired number of wave actuated members or prime movers.

A further object of my invention is to provide, -in a device of the class mentioned, improved means for regulating the speed of the power shaft.

Other objects will appear hereinafter.

Nith these objects in view my invention consists generally in providing a suspended weight which is raised by the reciprocation of a wave actuated vane and in providing suitable mechanism between said weight and a power shaft for driving the latter through the medium of the downward action of the weight.

My invention further consists in a device as mentioned further characterized by in terposing a ratchet mechanism in the connection between the weight and the power shaft whereby the latter is driven in one direction only upon the reciprocation of the weight.

My invention further consists in a wave motor as mentioned further characterized by a governor comprising a stationary member and a rotary member operatively connected to the power shaft, a brake shoe carried by the rotary member, a cam for actuating said shoe and a wing connected to said cam for operating the same.

My invention further consists in various details of construction and arrangements of parts, all as will be fully described herein after and particularly pointed out in the claims.

My invention will be more readily understood by reference to the accompanying drawings, forming a part of this specification and in which- Figure 1 is a diagrammatic side elevation illustrating my improved motor, Fig. 2 is a diagrammatic end view of the same, Fig. 8 is a detail sectional view of the speed regulator taken on substantially the line wm of .F 4-, and Fig. 1- is a transverse section of the same taken on substantially the line g of Fig. 8.

Referring now to the drawings, 1.1 indicate wave actuated vanes pivotally supported as at 2 upon suitable foundations or supports provided for the same. These vanes may be of any desired form but preferably similar to those described in my Patent No. 1,15%,038, issued September 21, 1915. These vanes are each provided with cables 3 to limit their forward or return movement. Secured to the vanes are power cables 4 which extend downwardly under idlers 5 and thence to the motor forming the subject matter of the present invention.

The cables l extend under idler-s 6 and thence upwardly and over pulleys 7 and upon the depending ends of the cables a are secured weights 88. It should be understood that there are as many cables f and weights 8 as there are vanes 1 and that the number is dependent upon the power it is desired to produce.

Arranged adjacent each of the weights 8 is a vertically disposed endless cable 9 passing over an upper pulley 10' and a lower pulley 11 and the weight 8 is secured fixed upon said cable as shown clearly in Fig. 1. in order that the pulley 10 shall be positively driven by the cable I prefer to arrange several bights of the cable about the pulley as indicated in Fig. 2. ft is obvious that with the reciprocation of the vane 1, by the action of the waves, the weight 8 will be raised and upon return of the vane to normal or vertical position the weight will drop thereby rotating the pulley 10 through the medium of the cable 9. In order that the shaft 12 upon which the pulley 10 is mounted shall be driven in one direction only, a suitable ratchet connection 13 is provided between said pulley and shaft.

Fixed upon the shaft 12 is a sprocket gear 14 which is connected by a sprocket chain 15 to a sprocket gear 16 on a shaft 15. Fixed to the shaft 15 is a gear 17 meshing with a gear 18 on a power shaft 19,

and the latter is equipped with a belt wheel 20 or equivalent device from which the closes the disk 22.

power may be transmitted to the work.

It is obvious that with the mechanism above described, the power shaft will be driven uniformly in one direction and in order that, with the reciprocation of the weights 8, the power shall be substantially uniform, I prefer to employ a number of vanes and cooperating weights and cables, although in the drawings I have illustrated but two, it being clearly understood that any number .may be employed without departing from the spirit of my invention or the showing made in the drawings.

In order to govern the speed of the motor I provide a novel regulator. 21 indicates a fixed or nonrotary shaft to which is rigidly secured a disk 22. 23 indicates a shaft in axial alinement with the shaft 21 and to which is secured a pinion 2i meshing with a gear 25 fixed to the shaft 15. A cage 26 is fixed to the end of the shaft 23 and in- Arranged within the cage 26 between suitable guides are brake shoes or blocks 27. Although any suitable means may be employed for guiding the brake shoes and maintaining them in position, I have illustrated the walls of the cage 26 as provided with ribs or bosses 28. Ad-

jacent each of the blocks 27 is a cam disk 29 mounted upon pintles 30. Each of the cam disks is provided with a radially extending arm 31 upon-which is mounted a wing 32 which forms a resistance element by engagingthe atmosphere. It is obvious that with the rotation of the device, the wings,

through the resistance of the air, will cause the cam disks to actuate the brake shoes and :that as the speed increases the shoes will be pressedwith greater force upon the periphery ofthe disk 22. In order to regulate the f device to the desired speed the wings 32 are adjustably mounted on the arms 31, it being obvious that the farther the wings are arranged from the center of rotation the quicker the brakes will act and therefore the slower the device will operate. The operation ofthe device is clear from the above description.

In a wave motor, a weight, a wave actuated vane, an endless cable having said weight secured thereto, means connecting said vane and said weight for raising the latter upon oscillation of the former, a pulley and pulley shaft, a ratchet connection between said pulley and said shaft for operating said shaft upon the fall of said weight,
